Overview: Simple forward proxy chaining example

In this example, Access Policy Manager (APM) performs simple forward proxy chaining from a BIG-IP system to a proxy server. Refer to
BIG-IP Access Policy Manager: Secure Web Gateway
for additional detailed examples of forward proxy chaining using different methods of authentication and single sign on.
To support this configuration, you need a per-session access policy, but no specific configuration is required in it. Because you are configuring proxy chaining for each request, you need to create a per-request policy that can select the next hop. The proxy servers to which you are sending the next hop need to have been previously set up, and organized in a pool.
For forward proxy chaining, APM requires an HTTP proxy connect profile configured with its state disabled. The HTTP proxy connect profile must be specified in the virtual server that processes the HTTPS traffic for the explicit or transparent forward proxy configuration. The per-request policy also needs to be associated with the virtual server that specifies the per-session policy.
